The campaign is limited to less than 2,000 vehicles from the 2018 model year.
Toyota has issued its second recall for the 2018 Camry, addressing a manufacturing screwup that can lead to engine failure.
Engines in approximately 1,700 vehicles may have been built with oversized pistons.
"In certain conditions, this may cause the vehicle to run rough, create an abnormal sound, emit smoke from the exhaust, and illuminate warning lights and messages," the company warns. "In some cases, a reduction of power may occur and the engine could stop running."
It is unclear if the problem has already led to failures in the field, though the NHTSA complaint database includes numerous reports of acceleration issues.
Vehicles that were built with one or more incorrect pistons will receive an entirely new engine.
